Part I of this Photo Gallery concentrates on the bulk-online Leaders and Sponsors, i.e. those companies which support the Powder/Bulk Portal most. Without them, this Portal would hardly exist. In the name of the global Bulkoholics community we extend our thanks to these presently about 35 companies.

We invite your feedback with corrections and additions of missing names, also for the respective eDirectory listings. Please email your comments to wohlbier@bulk-online.com . Your cooperation is very important for our worldwide leading bulk-online Information Center. We strive at the highest possible perfection, but without your continuous input and help we are bound to fail.

The importance of these Shows and also of our Photo Galleries and their enormous advertising potential, can be seen in the views figures of earlier Easyfairs venues (as of December 28, 2015).

One of the most important factors in determining the type of rotary dryer that is most appropriate for a certain process is the usage of direct or indirect heat. Rotary dryers are capable of utilizing either direct convection style heat transfer or indirect heat transfer, in which hot surfaces within the dryer provide heat by conduction and radiation. The determination of direct or indirect drying is contingent on the properties of the material to be dried, the process conditions and the desired end product.

Rotary dryers are versatile machines, and can be configured to meet a wide range of needs and applications. In terms of direct drying, hot air enters the rotating cylinder at one end, passes through it and exits at the other end. Flights welded to the internal walls of the cylinder lift and shower the wet material, bringing it into direct contact with the hot air. Configuration of the flights depends on the characteristics of the material being processed. This configuration is customized to efficiently handle the product as it flows through the dryer. The length and diameter of the cylinder are also customized according to the capacity of the dryer and the characteristics of the product.

Typically, a rotary dryer is filled to 10-15 percent of cylinder volume. The length of the cylinder is usually at least four times the diameter in order to achieve efficient heat transfer and temperature equilibrium between the product and the air stream.

The airflow in direct heat rotary dryers can be either counter or parallel to the conveyance of the material inside the dryer. Parallel flow dryers expose the wet feed material to the hottest air temperature. They are very efficient for handling high moisture content sludge and filter cakes. Because of the rapid heat exchange, there is significant evaporative cooling of the product. This cooling effect allows for drying a wide range of materials with varying heat sensitivities without thermally degrading the materials.

Counter flow dryers expose the driest material to the highest air temperature. This configuration is usually best for processes that require a specific elevated discharge product temperature or very low moisture content.

Indirect heat rotary dryers are most frequently used for products with small particle sizes that could result in excessive dust generation. They are also used for processes that require extreme control of the dryer exhaust. Indirect heat dryers depend on conduction and radiation to transfer the heat from the cylinder walls to the wet feed. A stationary furnace surrounds the rotary cylinder and heats the cylinder walls. Little or no airflow is required to pass through the dryer. Indirect dryers can provide only a limited amount of heat transfer area. They cannot efficiently handle materials that tend to stick to the heated walls of the cylinder.

Rotary dryers designed by Heyl & Patterson are built to each customer’s requirements. Because every dryer is custom engineered and the original drawings are maintained in-house, any unit can be serviced with upgrades or repairs according to its original specifications for the life of the equipment. Heyl & Patterson also provides superior customer support before, during and after the purchase on each product supplied by the company.

Designed to remove extruded material away and effectively start the pneumatic conveying process to the dryer from the extruder, the new Supplied Air Extruder (SAE) Hood from Schenck Process is loaded with innovations that are critical to the pet food manufacturing process.

thyssenkrupp has won a contract from Yamama Saudi Cement Company, one of Saudi Arabia’s biggest cement producers, to build two turnkey cement clinker production lines. The two lines with an overall capacity of 20,000 tpd cement will be built at a new site around 80 km east of the capital Riyadh. The value of the contract is in the higher three- digit million euro range. It is the largest cement contract ever secured by thyssenkrupp.

On November 4 and 5, 2015 these two powder/bulk trade shows took place in Dortmund, Germany:

Schüttgut (SOLIDS) + Recycling Technology

As in previous years, The Powder/Bulk Portal presents a Photo Gallery which may help future potential exhibitors and visitors to plan their attendance and visit.

The presentation is divided into 10 Parts (Part I to Part X). Please search specific Parts or companies in the Contents below:

Part I: The bulk-online Leaders & Sponsors.

Part I of this Photo Gallery concentrates on the bulk-online Leaders and Sponsors, i.e. those companies which support the Powder/Bulk Portal most. Without them, this Portal would hardly exist. In the name of the global Bulkoholics community we extend our thanks to these presently about 35 companies.

Rulmeca Corporation has published a new Motorized Pulley flyer for the convenience of bulk materials handling conveyor engineers and operators in North America. Filled with useful illustrations and technical information, this eight page document will help managers solve a variety of conveyor problems including conveyor drive reliability, abrasion, corrosion, size restrictions, belt slippage, belt tracking and extreme temperatures.

The SWB505 MultiMount™ weigh module now comes with new and improved load-cell technology for even higher accuracy that was possible before. It is easy and safe to install and has received OIML C6 and NTEP IIIM approvals for use in applications with a high-accuracy requirement.

The European Union plans to turn heavily towards using renewable energy in order to reduce emissions by 80 percent before 2050. They are focused on reaching this goal, not just through the use of solar and wind but also wood pellets.

Lincoln (NE), United States – Rotaries are a common point level indicator used for high-, mid- and low-level material detection in bins, tanks, and silos.
